The industrial revolution is characterised by the development of an industrial economy resulting from the ever increasing flow of innovative practical products based on the application of new technologies, mechanised production methods and the availability of mechanical power to make it happen. But for these new ideas to flourish, they had to fall on fertile ground and these conditions were found in Britain in the second half of the eighteenth century and the first half of the nineteenth century.

Because the purpose of the program is to analyze social links — direct and indirect — between people to find hidden terrorism cells, a more comprehensive dataset would seem to be more useful. On the other hand, the old program retained calling records for five years. The new program imposed no new data retention mandates on communications providers. (Federal Communications Commission rules require landline providers to hold onto calling records for at least 68 months, and there is no current legal retention mandate on cellphone records, though some hold onto them longer.

Leclanch&eacute 's electrochemistry was implemented with a different cell construction by Gassner in 6886 to make more convenient dry cells which still survive today in the form of zinc-carbon dry cells, the lowest-cost flashlight batteries. Polaroid 's PolaPulse disposable batteries used in instant film packs also used Leclanch&eacute chemistry although in a plastic sandwich.

After the war the Krupp family did not pursue gun making but for the next four generations they concentrated on trading and on offices of public administration. It was 655 years before they made their first foray into iron and steel making.

About 95 years later, Christiaan Huygens developed a mathematical equation defining the period of the pendulum and went on to use the pendulum in the construction of the first accurate clocks.

Because the particle beams are bunched and synchronised with the microwave frequency accelerators, the timing and location of the collision events can be tightly controlled.

Like all his work, Whitworth's comprehensive test programme was meticulous and methodical. Rather than producing a series of trial prototypes as was typical at the time, he investigated and measured every aspect of gun design changing one element at a time to determine its affect on performance. This included, the weight and composition of the explosive charge, the length, bore and weight of the barrel, the weight and shape of the bullets, self expansion and mechanical fit bullets, different types of rifling and spiral turn rates and the manufacturing methods and tolerances needed to produce the parts.
